Here's the pieces that I used. Sounds like Igor's approach is better,
but here it is if you can't do it that way.
in your css:
.invisible{
display: none;
}
.visible{
display: inline;
}
Now, the component side (proficiencyChoice is a dropdown)
proficiencyChoice.setOutputMarkupId(true);
//define the model that will return the stylesheet
(visible/not visible) for the select box proficiencyChoice
IModel modelForStylesheet = new Model()
{
public Object getObject( Component c )
{
if (mdl.isSelected())
return "visible";
else
return "invisible";
}
};
proficiencyChoice.add( new AttributeModifier ( "class",
true, modelForStylesheet ));
rvitem.add(proficiencyChoice);
